Reckoned to be wrong, when one considered fully (7,3)

I believe the answer is:

thought out

I'm a little stuck... Click here to teach me more about this clue!

'considered fully' is the definition.
'thought-out' can be an answer for 'considered' (thesaurus). I am not certain of the 'fully' bit.

'reckoned to be wrong when one' is the wordplay.
I cannot quite understand how this works, but
'reckoned' could be 'thought' ('think' can be a synonym of 'reckon') and 'thought' is found in the answer.
'wrong' could be 'out' (eg a calculation might be 'out') and 'out' is found within the answer.
No letters remain.
This explanation may well be incorrect...

(Another definition for thought out that I've seen is " Planned".)

I've seen this clue in the Evening Standard.
